BUTTON.

Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed March 3,1904. Serial No. 196,270.

To all whom it may concern:

Be it known that I, EDGAR SHANTZ, of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Button, of which the following is a specification.

This invention consists in buttons having Shanks composed of different material than their heads, and so constructed and connected to the heads as to resist to a maximum any strain tending to effect the detachment thereof, all as hereinafter fully set forth and pointed out in the claims.

In describing this invention, reference is had to the accompanying drawing, in which like characters refer to corresponding parts in all the views.

Figure l is a vertical sectional view of a button-head and its cast stem. Fig. 2 is a similar sectional view of the parts shown in Fig. 1, after surplus metal has been removed from the stem. Figs. 3 and 4 are, respectively, sectional view and elevation of the finished button. Figs. 5 and G are elevations, partly in section, of modified constructions of buttons embodying this invention.

Buttons having heads formed of pearl or other fragile substances are usually provided with metallic shanks.

`1n the manufacture of such buttons the Shanks have heretofore been secured to the heads by expansion of the metal forming the shanks.

To those skilled in the art, it is well known that when button-heads and Shanks are united7 as described, a large percentage of the heads is destroyed by breakage, even though slight expanding strain is used, and that the Shanks are but insecurely fastened to the heads, and frequently become detached therefrom, especially when in use and subjected to strain, thus rendering the buttons objectionable and tending to decrease the use thereof. By this invention, buttons of the described type are provided with Shanks which resist to a maxi-` mum any strain tending to detach the same.

A is a head composed of pearl, or other fragile substance, and having a socket a opening in the rear face thereof and increasing inwardly in size.

B is a shank composed of metal and having one end Cast in the socket. The shank B is preferably cast under pressure. By uniting the head and the shank as described, the shank entirely fills the socket a, is securely fastened to the head A without material strain upon said head, and resists to a maximum any force tending to effect the detachment of the headl and shank.

The cast stem, as illustrated, may be formed of greater size than the button-shank to be produced therefrom.

When the stem is so formed, its free end is engaged by the hand or a suitable tool, and the portion thereof adjacent to the button-head is reduced in size, after which the projecting end of the stem is cut off, whereupon the.

unfinished shank is of the form seen in Fig. 2. The free end of the unfinished shank is subsequently flattened and perforated, thus causing the same to assume the construction and form seen in Figs. 3 and l. It is sometimes desirable to provide one of these buttons with a suitable fastening device, in which event the shank is produced as described, but the projecting part of the cast stem is cut off close to the rear face of the button-head, as seen in Fig. 5, and the fastening device e5 is secured to the outer face of the shank in any desirable manner, as by soldering. Moreover, if desired, a button having a short shank of the type illustrated in Fig. 5, may be unprovided with a fastening device and formed with a perforation c6 extending through its shank in close proximity to the rear face of the head, as seen in Fig. G.

The construction and operation of a button made in accordance with this invention, will now be readily understood upon reference to the foregoing description and the accompanying drawing, and it will be particularly noted that this invention is not limited to any special forni of shank.

What I claim is:-

1. As a new article of manufacture, a button comprising a button-head formed of pearl or other fragile substance, and having a socket opening in its rear face and increasing inwardly in size, and a metallic shank having one end cast within said socket, substantially as and for the purpose described.

2, As a new article of manufacture, a button comprising a button-head formed of pearl or other fragile substance, and having a socket opening in its rear face and increasing inwardly in size, and a metallic shank composed of metal cast under pressure, said shank having one end cast within the socket, substantially as and for the purpose specified.

3. In combination, a button-head formed of pearl or other fragile substancel and having a socket opening in its rear face, and a metallic stem havingr one end cast within the socket and having the portion thereof projecting beyond the rear face of the head formed of greater' size than the finished button-shank to be produced therefrom, substantially as and for the purpose set forth.

In testimony whereof, I have hereunto signed my name in the presence of two'attesting witnesses, at Rochester, in the county of Monroe, in the State of New York, this 16th day of December, 1903.

EDGAR SHANTZ.
